[Bug 272811] Re: too high cpu usage

[kickaha]

I have this same problem. Firefox and Xorg start to thrash when I hit
some web pages. This same behaviour also occurs in Galeon, but not in
Opera or Konqueror.

Software:
Ubuntu 8.10
Kernel: 2.6.27-7-generic
Gnome 2.24.1
firefox 3.0.4
galeon 2.0.6

Hardware:
Intel Core 2 Duo
4GB DDR2 memory

Add-ins, Plug-ins:
noscript 1.8.6
ubuntu firefox modifications 0.6
demo print plugin
divx web player
quicktime 7.2.0 (totem 2.24.3 plugin)
shockwave flash 9.0 r999
shockwave flash 9.0r124
Totem web browser 2.24.3
windows media player plugin 10 (totem 2.24.3 plugin)

I'm having problems on some pages, but not all. It is especially bad when I load a page that has flash or other video. I don't even have to play the video, just accessing the page will cause xorg and firefox to consume at least one full core of cpu time.
leaving the page(s) or closing them doesn't always clear the cpu overload. Sometimes I have to kill firefox externally.
one example page is www.dailykos.com.

This same behaviour also occurs with galeon , but not with Opera.
